I always find it maddening when people have the gall to critique a performer like BeyoncÃ©, questioning her star power, or entertainment value, or (gasp!) singing voice. Itâ€™s akin to the flunky armchair quarterback, sitting at home saying he would have caught that pass. HA! Iâ€™d like to see you try. You absolutely cannot step toÂ BeyoncÃ© or her singing abilities â€” and particularly her balls out Super Bowl halftime performance Sunday night. And you also canâ€™t step to Beyâ€™s backing band, the Sugar Mamas, who bring with them scads of musical experience and sweat equity in the biz.
